Scaled power line based network

摘要

A power line communication (PLC) network includes a plurality of PLC devices. One such PLC device may include a transmitter power control system that determines a minimum level of transmission power for sufficiently communicating a plurality of data packets from the PLC device over the PLC network to a first destination PLC device on the PLC network by executing a training sequence over the PLC network via an electrical power distribution system. The transmitter power control system applies this minimum level of transmission power to transmit the data packets to the first destination PLC device.

1. A power line communication (PLC) device comprising:
a transmitter power control system configured to determine a first level of transmission power for communicating a plurality of data packets from the PLC device over a PLC network to a first destination PLC device on the PLC network by executing a training sequence over the PLC network via an electrical power distribution system and to apply the first level of transmission power to transmit the data packets to the first destination PLC device; wherein the first level of transmission power enables the PLC device to transmit the data packets to the first destination PLC device, but not to a second destination PLC device on the PLC network, and wherein executing the training sequence comprises:
repeatedly transmitting from the PLC device to the first destination PLC device using successively reduced transmission power levels until the first destination PLC acknowledges receipt with a predetermined level of received signal power; andselecting the transmission power level that resulted in the first destination PLC device acknowledging receipt with the predetermined level of received signal power as the first level of transmission power.
